摘要:
Controlling a flowing direction of expelled urine so as to flow along a concave groove side even when the absorbent article is laterally shifted while being worn, and causing the absorbent body to absorb the urine rapidly without causing side leak by enlarging the reserving volume of the concave groove. In an absorbent article in which at least a single concave groove (22) for flowing urine therein is formed at a skin side surface along a longitudinal direction, a transverse plane shape of the concave groove (22) is formed to satisfy following conditional expressions (1) to (3), (1) a relationship between a depth "h" of a bottom surface portion of the concave groove, and a distance "S" from a bottom end "G" of the concave groove to an upper end "K" from which a concavity of the concave groove starts is 1.5h < S, (2) a relationship between a width "b" of a bottom surface of the concave groove, and a width "B" of a liquid collection area expressed by a distance between the upper ends "K" and "K" at both sides of the concave groove is B ‰¥ 3b, and (3) a relationship between a dimension "a" of a square concave groove expressed by a product of the width "b" of the bottom surface of the concave groove and the depth "h" of the bottom surface portion, and a cross-sectional dimension "A" of the concave groove is A ‰¥ 2a.
